2.勾选Web模块,DevTools可不选(用作热部署,不影响运行)

3.创建完成后,项目结构如下图:

4.pom.xml文件中添加jsp的依赖

        <dependency> <groupId>org.apache.tomcat.embed</groupId> <artifactId>tomcat-embed-jasper</artifactId> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> </dependency>

5.在application.properties文件中添加以下内容:

#路径,在webapp文件夹下新建文件夹WEB-INF,在往下建文件夹jsp spring.mvc.view.prefix=/WEB-INF/jsp/ #文件名的后缀,例如:index.jsp,放在jsp文件夹下 spring.mvc.view.suffix=.jsp

.yml 文件配置如下:

spring:
    mvc:
        view:
            prefix: /WEB-INF/test/
            suffix: .jsp

6.新建index.jsp文件,路径结构如图:

7.index.jsp页面内容如下:

<%@ taglib prefix="spring" uri="http://www.springframework.org/tags"%> <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%> <%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%> <!DOCTYPE html> <html> <head> <meta charset="UTF-8"/> <title>登录</title> <link rel="stylesheet" href="<%=request.getContextPath() %>/css/signin.css"> <link rel="stylesheet" href="<%=request.getContextPath() %>/css/bootstrap.min.css"> <style type="text/css"> body { padding-top: 50px; } .starter-template { padding: 40px 15px; text-align: center; } </style> </head> <body> <nav class="navbar navbar-inverse navbar-fixed-top"> <div class="container"> <div class="navbar-header"> <a class="navbar-brand" href="#">Spring Boot+JSP</a> </div> <div id="navbar" class="collapse navbar-collapse"> <ul class="nav navbar-nav"> </ul> </div> </div> </nav> <div class="container"> <div class="starter-template"> <h2>登录</h2> <form class="form-signin" role="form" name="form" action="/login" method="post"> <div class="form-group"> <label for="username">用户名</label> <input type="text" class="form-control" name="username" value="" placeholder="用户名"/> </div> <div class="form-group"> <label for="password">密码</label> <input type="password" class="form-control" name="password" placeholder="密码"/> </div> <input type="submit" id="login" value="Login" class="btn btn-primary"/> </form> </div> </div> </body> </html>

8.引入css文件,这个不影响效果,只是index.jsp的页面会不好看

9.新建IndexController.java

package com.example.demo.controller; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; @Controller public class IndexController { @RequestMapping("/index") public String index() { return "index"; } }

如果想使用restcontroller注解，需要以下处理

@GetMapping("/order")
public ModelAndView toPayJsp() {
// return
// "pay_wx";//@RestController注解含有@ResponseBody注解,结果pay_wx没有经过视图解析器解析直接变成json字符串返回给浏览器了
ModelAndView mv = new ModelAndView("pay_wx");
return mv;
}

10.启动服务,访问localhost:8080/index 即可访问index.jsp成功
